re: What is something you have developed an allergic reaction to as you have aged?

Believe it or not, cashews share some traits with poison ivy.

The anacardiaceae family of trees, sometimes called the cashew family, includes mango, poison ivy, poison oak, sumac, Peruvian pepper, pistachio, and you guessed it, cashews. They all contain urushiol, the sneaky oil that causes the skin to erupt in rashes for some people and is the bane of my existence, but to varying degrees. The oil is found in all parts of the plant, including the leaves, stems, and even the roots.

Stainless steel. Not 100% sure whether it’s nickel or chromium, but I’ve broken out from leather contact as well which makes me think chromium.

Sucks. Can’t wear watches anymore without getting contact dermatitis.

I found out I was allergic to food coloring a couple years ago. Could be a specific ingredient in one of the colors, but a few years ago I had a reaction from eating a piece of King Cake that had food coloring icing.
My tongue swole up to where it was difficult to breathe through my mouth. Happened a couple more times since then, and I just made the connection with each incident, that it was food coloring.

From then on I don’t eat anything that was dyed with food coloring and I haven’t had a reaction since.
